#18: Villa Vittoriosa, Georgia: 44,234 sq ft
The Maltese-inspired mansion, Villa Vittoriosa, is reported to be the biggest family residence in the state of Georgia. The former home of boxer Evander Holyfield is housed within an estate which includes a 4,000 square foot guest house and a seven-stable barn.
The grand entrance hall features an impressive marble floorwork design that extends from the center of the room. Dual staircases lead down from the balcony surrounded by gold-embellished Roman-style pillars.
There are a total of 12 bedrooms and 21 bathrooms, as well as a bowling alley and a dining room fit for 100 guests. The walls of the interior living spaces are wood-paneled and ornate, while a long marble and mirror swimming pool room offers space for an indoor dip.
Outdoors, the expanse of the property becomes clear, as the vast white mansion provides a backdrop to grounds spanning over 100 acres. The outdoor pool is allegedly one of the largest in the United States and is overlooked by multiple balconies from the main house.
